[2]House dust mites (HDM, or simply dust mites) are various species of acariform mites belonging to the family Pyroglyphidae that are found in association with dust in dwellings. [3]
The first allergen to be purified and characterized was Der p 1, in a 1980 study by Martin D. Chapman and Thomas Platts-Mills. [10] [11] By the end of the decade, it was suspected that Der p 1 was a cysteine protease when its structure showed similarities to that of actinidin and papain. [12]
The IgG, IgE and IgA antibody isotypes are generated following class-switching during germinal centre reaction and provide different effector functions in response to specific antigens. IgG is the most abundant antibody class in the serum and it is divided into 4 subclasses based on differences in the structure of the constant region genes and ...
Dermatophagoides pteronyssinus, the house-dust mite is the best known species causing such problems. [14] Mites causing similar problems are in the genera Acarus, Glycyphagus, Tyrophagus, and others. Cytodites nudus respiratory mite
